Abstract
This review covers the volatile organic compounds (VOCs) emitted by the bodies and secretions of introduced mammalian predators in New Zealand forests, with a specific focus on mice, rats, ferrets, stoats, and possums. The primary aim is to compile information on these VOCs and assess the potential of exploiting these VOCs as unique biomarkers for predator detection in the forest. While a universal VOC has yet to be identified, the review discusses various VOCs associated with predators and their potential as unique biomarkers for detecting the presence of predators, including 2-heptanone, 4-heptanone, 2-octanone, and benzaldehyde. Furthermore, a brief overview of different VOC detection techniques is provided, connecting the selection of biosensing techniques with the detection of volatile biomarkers. Further research and advancement in the biosensing field hold substantial potential to enhance biomarker detection technologies and elevate predator management strategies within New Zealand forests.
